Using High Speed Inputs with 12-24 Volt Signals

Most PLCs don’t use 5 volt logic. You can connect signal levels as high as 24 volts to the STEP and DIR

inputs if you add external dropping resistors, as shown below.

• For 12 volt logic, add 820 ohm, 1/4 watt resistors

• For 24 volt logic, use 2200 ohm, 1/4 watt resistors

The maximum voltage that can be applied to an input terminal is 24 volts DC.

Never apply AC voltage to an input terminal.
